A nttnqi n arest; 6., 1,898: sum nt seazza on model) ToaZZ whont as ma06mm": 1 k Be it known thatI, EDWIN CHILDREN, a eiti zen of the UnitedStates, residing at Council- Bluffs, in the county ofPottawattami-e'"and l- -yieldingly secured to the axle and connectedState of Iowa, have invented certain new and i useful Improvements inWheel-(Jultivators;

and I do hereby declare the following tobe a 'full,jclear, and exactdescription of thein'ven tion, such as willnenable others skilled inthe.

art to which it appertains to make andmse. the

same.

This invention relates to an improvement 1 in wheelfcultivators and itconsists inthe construction and arrangement of parts hereinafetor-described and definitely pointed outin provide a edltivator of thenature abov'e indiv carted, and to so construct thesame that, the meritsof thelshallow scraping action of the disks may. be'employed with themore thorough working of the shovels or shares, and to -'so arrange thesame that the shovels'w'illact directlyon the disks with a tendency tohold them to their work and increase their penetration'into the soil,and also to thoroughly work-up or cultivate thesoil at a point centrallybetween the rows and path of the outer disks so that the soil betweenthe rows will be structionjllu'strated in the accompanying moisture, andprevented from crustiug or baking. These objects are attained by the condrawings wherein like letters of reference indicate corresponding partsin the several views, and in which-. Y

In the drawings A represents the axle mounted on suitable wheels. Tothis axle is attached the frame work consisting of two oblique bars a aconnected at their outer ends and between which the pole B isloosely'held and pivoted; O is the handilever pivotally sp-pported onthe pole and connected at its forward smite, one of the-oblique bars.'C" "indicate-the :reach bers-pivotally and at their outer'endsto thecross yoke D To the outerjends of {the latter the plowbeams'l) arepivotallyand adj ustably secured, and extend back below and in the rearof the axle;

:leys. t I i The construction above described with the exception oflevers G and pulleys, is the same as that shown'in my patent,No.434,765, and

the lower ends of which pass the pins g. The

pins 9' are formed on a metallic frame G" rigid on the beams. Theseframes G have a forwardly extending arm g which extends slightly abovethe plane of the tops of the beams, and carry at their forwardeuds-jour-- nals'g on which the pulleys f are mounted,

flanged wearing plates 9 being secured on the beams below the pulleys.The upper por-' tions of thefrai'nes G have segmental racks G: formedthereon with inclined teeth with which'an inclined .tooth on thelevers'G euga ges I i I To hold the tooth on the lever in engagementwith the teeth of the rack, and to peropenings in their heads on thepins.

To move the teeth out of engagement, when the plows are to be lowered,it isonly necessary to press laterally on the levers, the open-- ingsthrough which the pins pass being-sulficiently large to permit suchmovement without binding; The springs immediately force the teeth intoengagement when the lateral pressure is removed. ,The inclination of theteeth permit the raise the beams. 1

On the under side of the beams midway their length are secured thedisk-supporting shafts I-I extending on opposite sides of the beams thesame being preferablyadjustably applied thereto. these shafts Ii aresecured the vertical standards 11 extending lower ends carrying journalboxes it. These boxes are arranged obliquely to the plane of the beams,and have upwardly extending connecting plates 71. formed with circularbolt lower .ends and curved elongated openings 71. in their upper ends,suitable bolts being passedthrough the openlever to be moved back to Onthe, opposite ends of downward and on their ings and lower endsofflthersiandards. there.

being spacing blocks h interposed. By this means the pitch of the disksmay be alteredby simply loosening the nuts on the bolts passing throughthe elongated slots. H indicate the concave-convex disks (two in numheron each side) usually having the stub axles h on their convexed centerswhich are journaled. in the boxes h the disks being at the inner ends ofthe boxes. These disks are used for the shallow cultivation of thesoilat a point adjacent to the roots of the plants and do not act on thesoil centrally between the rows.

To thoroughly'cultivate and act on the soil intermediate the rows. orbetween the space acted on by the disks, and where the roots of theplants will 'not be materially interfered with, and to hold the disks totheir work, I arrange on the outer sides of the beams at their rearextremities the plow standards K.

the standards which have their lower points inclining for- Thesestandards are secured to the beam in any snitablemanner. On the lowerends of K are the shovels or shares L ward and downward, thereby havinga penetrating tendency when moving, which tends to hold the disks totheir work. By this arrangement it will be seen that the shovels orshares travel in a path slightly beyond but in operative proximity tothe path of the outer disks, and they are carried down to points belowthe plane ot the lowest points of the disks, thereby thoroughly anddeeply cultivating the soil at that point. By the operative proximity ofthe shovels to the path of the disks the former breaks surfaces left bythe scraping action of the outer dlSkS.'

By the above described construction it will be seen that theessentiaLfeature of the invention is the improved manner of combiningthe disks with the shovels orjshares so that the beneficial result ofboth maybe ob tained,resulting in a the soil.

In arranging the beams adjustable at their forward and rear ends, asdescribed herein and shown in my patent above referred to,

thorough cultivation of ,I am enabled to readily change the relative thelatter be planes of the disksand shovels, ing on the extreme .rear endsof the beams and the former on the same beam but inter- "mediate theends, so thatas the beam is adjusted up or down vary their'holding downtendency onthe disks, cally elevated to penetrate the crust only, whilethe shares arefpermitted to deeply cultivate the intermediate soil. Itwill also be seen that this essential feature is applicable to otherforms of cultivators.

theshares will have an increased or decreased-penetration and therebyand further the disks may be practiup and covers the smooth I am awarethat many minor changes in the construction and arrangement of the partscan be made and substituted-for thosehereiu' shownand described withoutin the le'astde parting from the nature andprinciple of my invention.
